Solution
Step 1
We first name the constant leakage rate r.
r = 1200 milliliters per hour
Step 2
We then find the time in hours to leak one milliliter by dividing one milliliter by r.
t = 1 milliliterr
Step 3
We then convert the time from hours to seconds by using that one hour equals 3600 seconds.
t = 1/1200 hours per milliliter t = 1/1200 3600 seconds per milliliter t = 3 seconds per milliliter
Answer
3 seconds
